SPRINKLER.

Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed March 14, 1913. Serial No. 754,231.

To all whom it may concern:

Be it known that I, J OI-IN P. CAMPBELL, a

citizen of the United States, residingat Jacksonville, in the county ofDuval and State of Florida, have invented certain new and usefulImprovements in Sprinklers, of which the following is a specification.

My invention relates to certain new and useful improvements insprinklers designed to be used for irrigation and other similar purposeswherein it is desirable to cover uniformly as large an area as possiblewith Water.

One object of my invention is to provide a device of this character inwhich a main stream is thrown from the nozzle as a solid stream, that isto say is not broken up at the nozzle, whereby the stream will be thrownto a greater, distance than is possible were it so broken at the nozzle..7

By my invention I further provide a secondary stream which is adapted tocover the area within that covered by'the main stream,

said secondary stream operating to rotate the nozzle of the main stream.

A further object of my invention is to provide a denice of'thischaracter in which the passages therethrough are entirely unobstructed,so that thedevice will operate on a much lower pressure than is possiblewith sprinklers in which the dischargeis broken up at the dischargeorifice.

A further object of my invention is to provide a means for automaticallycontrolling the speed of rotation of the sprinkler, so that it willrotate at the proper speed to give the maximum sprinkling effect inspite of changes that may occur in the water pressure.

A further object of my invention is to provide a sprinkler simple andcheap in construction, efficient in operation and not likely to get outof order. Furthermore, to have it so constructed that it will not belikely to become clogged up with sediment,

pipe scale, or other matter that maybe in I the water.

With the foregoing and other objects in view my invention consists incertain constructions, combinations and arrangements of parts, thepreferred form of which will be first described in connection with theaccompanying drawings, and then the invention particularly pointed outin the appended claims.

Referring to the drawings wherein the Y same part is designated by thesame reference numeral wherever it occurs, Figure 1 is a perspectiveview of the preferred form of my sprinkler mounted upon a suitablesupport; Fig. 2 is'a central longitudinal section of the-sprinkler headshown in Fig. 1 and, Fig. 3 is a top plan view of the device. For thesake of illustration I have shown my invention as mounted upon avertical pipe 1, mounted upon a base 2 provided with legs 3 extendingfrom the side thereof, the

vertical pipe 1 being suitably connected within the base to a pipe 4, towhich can be secured the end of the hose 5 to supply water to thevertical pipe.

The preferred form of my sprinkler comprises a tube 6 formed at itslower end, with a portion 7 preferably enlarged as shown and provided onits interior with threads 8,

whereby it, can be threaded to the pipe to which it is to be connected,such as the pipe 1 shown in the drawing.

Thetube 6 is provided at its upper end with an outwardly extendingflange 9, which forms the upper side of a raceway for the balls 10, thelowerside of the raceway being formed by a ring 11 connected to a sleeve12,

the upper end of which is formed into a head 13, which extends over theend of the tube 6. The ring ll'is preferably secured screws 14, asshown.

.Secured in the-- head 13 by any suitable means,- as the screw 15, is apipe 16 which extends down through the tube 6- to the en larged portion7 thereof, and forms the water conduit from the enlarged portion 7 tothe angularly disposed main nozzle 17,

. which is threaded into the upper end of the pipe 16. 18 designates alook not which I may use to secure the main nozzle from rotation.

. 19 designates a secondary nozzle threaded into an opening in the sideof the head 13, therebeing formed an opening throu h the pipe 16 in linewith the opening in t e head into which the pipe 19 is threaded,

whereby a secondary stream can pass from the pipe 16 out through thesecondary nozzle 19. This secondary nozzle is bent into the form of anelbow and is turned at an angle so as to form a reaction element androtate the head 13 and with it the pipe 16 and the main nozzle 17. Asshown, the secondary nozzle 19 discharges obliquely and downwardly ontoa circular disk 20 fast on 1n position in the sleeve 12 by means of thethe tube 6, the same being shown assecured in position by a. setscrew.21. This plate may, as shown, he provided with radiallydisposed'ribs 22, against which the stream of water discharged from thesecondary nozzle 19 strikes to augment the rotating effect on the headand to distribute the water from said nozzle, though it'is evide-nt, ifdesired, that this plate can be entirely omitted, and the reactiveeffect of the stream on the atmosphere be relied on.

It is desirable, in order to produce the best effect, that the speed orrotation of the sprinkler be maintained uniform, and for this purpose Ihave shown the head as pro-' vided with a means whereby the angle of there-actio-n nozzle 19 may be varied according to the speed of rotation ofthe head, and in the form of invention shown this governor comprises alever 23, pivoted at' 24. to the head 13, one end of the lever having aweight 25 secured thereon, said weight beingpreferably adjustable on thelever as by having the end of the lever pass through a hole 26 in theside of the weight and providing a set screw 27 extend ng through theweight and into the opening to clamp the weight in its adjusted positionon the lever. As a means for connecting the opposite end of the leverfrom that carrying the weight to the re-ac-tion nozzle 19, I have shownthe nozzle as being provided with a clip formed at one'end into a'tube28, and split at its other end portion whereby the nozzle will beencircled and the split ends drawn together by ascrew 29, so as tosecurely clamp the clip on the reaction nozzle. Into the open end of thetube there loosely extends a screw 30, which is threaded into the end ofthe lever 23. It is to be noticed that the weight in its normal positionas shown in Figs. 1 and 2 is below the pivot 24 of the lever, so that asthe head 13 is rotated centrifugal force will tend to raise the weightinto the plane of the pivot 24. This through the screw 30 will operateto turn the nozzle down or toward its vertical position, so that thestream of water therefrom will strike the re-action plate 20 at a moreobtuse angle and decreasethe reaction effect. It is to be understoodhowever that where no re-action plate is used but the re-a'ctive effectof the atmosphere is depended on, the reaction tube may be arranged soas to be moved either up or down from the horizontal plane of rotationof the inner end of the tube to decrease the reactive effect and producethe uniformity of speed of rotation desired.

It is to be observed that the main nozzle 17 will throw a stream ofwater the maximum distance, and that the stream will leave the nozzlesolid, thus sprinkling an area beginning at some considerable distanceaway from the sprinkler.

reaction nozzle 19 will however, either by striking the plate 20andbeing thrown horizontally therefrom, or by directly throwing the waterinto the air, cover the remainder of the area between the inner edge ofthe area covered by the main sprinkler and the sprinkler itself.

I am aware that considerable variation is possible in -the detailsofconstruction herein shown and described, without departing fro-mthespirit of invention, and I do not intend to limit myself thereto, exceptas pointed out in the following claims, in which it is my intention toclaim all the novelty inherent in the structure shown and described asbroadly as the state of the art will permit.
